OLIVER PALM, OF ALBANY, TEXAS.

CH'URN-OPERATING DEVICE.

Specification of Letters Patent.

Patented Mar. 23, 1915,

Application filed November 13, 1912. Serial No. 731,163.

To all whom it may concern:

Be it known that I, OLIVER PALM, a citizen of the United States, residing at Albany, in the county of Shackelford and State of Texas, have invented new and useful improvements in ChurirOperating Devices, of which the following is a specification.

This invention relates to churn operating devices, and it has for its prime object to produce a simple and efficient mechanism for actuating or operating a churn of the reciprocatory type.

A further object is to produce simple and efficient mechanism whereby the dasher of a churn may be rapidly, evenly and steadily actuated so as to produce butter in the shortest possible time.

lVith these and other ends in view which will readily appear as the nature of the invention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited,

oisal taken on the line 33 1 a horizontal sectional line t4-. in Fig. 2. Fig. "tional view taken on the V Fig. 6 is a horizontal Y taken on the line 6-6 in oorres'oonding parts in the several figures are denoted by like characters of reference.

it plurality of brackets or supporting port 4- which may be the wall of a room, boiigh any convenient supporting structt e may be used. The brackets or supportmembers 1 are approximately W-shaped, will be best seen in Fig. 41, where the icket 1 is shown in plan; it being underod that the several brackets are of similar and. Fig. 3 is a ver-- members 1, 2, 3 are secured to an upright construction, but that 1 is the lowermost of the series and 3 the topmost one. The brackets 1 and 2 support clamping frames, each composed of rear and front meinliers 5 and 6 which are connected together and with the brackets 1 and 2 by means of bolts 7, vertical frame members 8 being interposed between the frame members 5 and 6 and held securely by means of the bolts or connecting members 7 so as to constitute the vertical side members of the frame structure. The frame members 5 and 6 also serve to clamp between them a pair of vertical guides 9 between which a cross head 10 is guided for vertical reciprocation.

The brackets 1, 2 and 8 serve to support a centrally disposed vertical frame support 11 having at its upper end a forwardly er:- tending arm 12 which is connected with the front member 6 of the clamping frame as sociated with the supporting bracket 2 by means of a front frame bar 13 which is reinforced bya web and which is equipped with bearings for shafts 15 and 1G. The shaft 16 carries a crank disk 17 and a pinion 18, which said crank disk and pinion may be formed integral with each other, as shown. The shaft 16 may also, as shown in Fig. 1 of the drawings, be extended forwardly and equipped with a driving pulley 19 adapted to receive motion from any suitable source of power, such as an electric or an internal combustion motor. The shaft 15 has been shown as carrying a gear wheel 20 meshing with the pinion 18 and also a crank 21 whereby the machine may be m anually operated. The crank disk is provided with several threaded apertures 22 at various distances from the axis thereof, and one of said apertures is equipped with a wrist pin 23 which may be shifted from one to another of said apertures for the purpose of varying the stroke of the pitrnan 2- whereby said wrist pin is connected with the cross head 10, the connection being effected by means of a second wrist pin 25, as best seen in Fig. 3. The side members 8 of the frame structure are extended above the supporting bracket 2, as will be clearly seen in Fig. 2 of the drawings, and the upper e2- tremities of said side members are connected with the rear frame bar 11 and with the front frame bar 13 by means of a reinforcing frame 26.

The side members 8 of the frame structure are extended downwardly and curved in the direction of each other to support a clamping device consisting of two semi-circular members 27, 28 connected together at one end by a hinge 29 and at the other end by a clamp screw 30. The members 27, 28, the former of which is fitted upon or other- Wise firmly secured to the lower ends of the frame members 8, combine to form a hoopshaped clamp, whereby the churn body 31 may be firmly clamped and held in position for operation. Said churn body which is of cylindrical shape and which may be constructed of sheet metal or other suitable material, galvanized or otherwise protected against corrosion, is provided near its upper edge with an exterior circumferential bead 32 adapted to rest upon and to engage the upper edge of the supporting hoop formed by the clamp members 27, 28, which latter, by tightening the screw 30, will thus tightly clamp the churn body and hold it immovably in position for operation. The churn body is provided below the bead 32 with an interior circumferential bead 33 which serves the double purpose of support ing the rim or flange 3a of the lid 35 and also of constituting a guard to prevent the contents of the churn from leaking between the flange 3% and the top of the churn body when said contents is being agitated during the operation of the device. The lid 35, which is concave on its upper side or face, is provided with a centrally disposed funnel 36 through which the dasher staff 37 is guided and which also serves to enable hot or cold water to be introduced into the churn without removing the lid, as may be needed for the purpose of bringing the contents of the churn to the proper temperature for facilitating the process of churning. The funnel 37 also serves to return .to the churn any liquid that may splash out between the walls of said funnel and the dasher staff. A superimposed cover or roof as it may be called of conical shape is provided, as shown at 38, said roof or top cover being provided with a central aperture 39 for the passage of the dasher staff, and with a notch 40 to enable it to be removed and replaced, as may be desired, said notch being sutliciently wide to admit of the passage of the dasher staff. This top cover or roof constitutes a protection to prevent lubricating oil from the machinery above, as well as dust or other impurities, from entering the churn while the operation is in progress.

The cross head 10 is provided with a clamping member 40 connected therewith by a hinge 41 and adapted to be secured by a screw 42 for the purpose of tightly securing the dasher staff with reference to the cross head. It will be seen that by simply loosening the screw 42 the cross head may be disengaged from the dasher staff, thus enabling the latter to be removed from the churn, the lid having been previously detached.

The dasher staff carries at its lower end the dasher head 43 which may be of any ordinary well known and approved construction.

As will be seen from the foregoing description taken in connection with the drawings hereto annexed, I have provided a simple and very efficient churn structure, whereby the dasher of a churn may be re ciprocated quickly, evenly and effectively with but slight effort or expenditure of power.

The churn is extremely simple in construction and may be easily kept clean and in a sanitary condition.

It has been found that by this mechanism butter may be made in as short time as this result may be effectively and properly ac complished by any method in present use.

Having thus described the invention, what is claimed as new, is

1. In a device of the class described, a plurality of brackets arranged in vertical series, a rear frame bar mounted on said brackets and having a forwardly extending arm at its upper end, clamping frames mounted upon and associated with the two lowermost brackets, a front frame bar connecting the uppermost clamping frame with the forwardly extending arm of the rear frame bar, vertical guide members supported by the clamping frames, a cross head mounted for vertical reciprocation between the guide members, a shaft supported for ro tation on the front frame bar, a crank disk on said shaft, a pitman connecting the crank disk with the cross head, and means for driving the crank disk carrying shaft.

2. In a device of the character described, a plurality of supporting brackets arranged in vertical series, clamping frames mounted on some of said brackets, vertical frame members supported by the clamping frames and extending below the lowermost clamping frame, vertical guide members supported by the clamping frames, a cross head guided between the guide members for vertical reciprocation, means for actuating the cross head, and a clamping hoop comprising two hingedly connected members, one of which is secured on the downwardly extended ends of the vertical frame members.

In testimony whereof I affix my signature in presence of two witnesses.

OLIVER- PALM.
